What is included in this cylinder kit?

This kit includes a Cylinder Works cast aluminum cylinder with a nickel silicon carbide bore, a Vertex piston, and all the necessary gaskets to complete the installation and restore your engine's performance.

Why is the nickel silicon carbide bore important?

The NSC electroplate bore allows for tighter tolerances, which reduces friction during piston movement. It also provides extreme durability, helping the cylinder last longer under demanding conditions.

How does the honing process affect performance?

The precision diamond honing ensures the cylinder bore is finished to exact dimensions. This is critical for achieving a proper seal with the piston rings and for effective oil retention, which keeps the cylinder walls lubricated and reduces wear.
